Constructor Detail

EscapedErrors

public EscapedErrors(Errors source)

Create a new EscapedErrors instance for the given source instance.

Method Detail

getSource

public Errors getSource()

getObjectName

public java.lang.String getObjectName()

Description copied from interface: Errors

Return the name of the bound root object.

Specified by:

getObjectName in interface Errors

setNestedPath

public void setNestedPath(java.lang.String nestedPath)

Description copied from interface: Errors

Allow context to be changed so that standard validators can validate subtrees. Reject calls prepend the given path to the field names.

For example, an address validator could validate the subobject "address" of a customer object.

Specified by:

setNestedPath in interface Errors

Parameters:

nestedPath - nested path within this object, e.g. "address" (defaults to "", null is also acceptable). Can end with a dot: both "address" and "address." are valid.

getNestedPath

public java.lang.String getNestedPath()

Description copied from interface: Errors

Return the current nested path of this Errors object.

Returns a nested path with a dot, i.e. "address.", for easy building of concatenated paths. Default is an empty String.

Specified by:

getNestedPath in interface Errors

pushNestedPath

public void pushNestedPath(java.lang.String subPath)

Description copied from interface: Errors

Push the given sub path onto the nested path stack.

A Errors.popNestedPath() call will reset the original nested path before the corresponding pushNestedPath(String) call.

Using the nested path stack allows to set temporary nested paths for subobjects without having to worry about a temporary path holder.

For example: current path "spouse.", pushNestedPath("child") -> result path "spouse.child."; popNestedPath() -> "spouse." again.

Specified by:

pushNestedPath in interface Errors

Parameters:

subPath - the sub path to push onto the nested path stack

See Also:

Errors.popNestedPath()

popNestedPath

public void popNestedPath()
                   throws java.lang.IllegalStateException

Description copied from interface: Errors

Pop the former nested path from the nested path stack.

Specified by:

popNestedPath in interface Errors

Throws:

java.lang.IllegalStateException - if there is no former nested path on the stack

See Also:

Errors.pushNestedPath(java.lang.String)

reject

public void reject(java.lang.String errorCode)

Description copied from interface: Errors

Register a global error for the entire target object, using the given error description.

Specified by:

reject in interface Errors

Parameters:

errorCode - error code, interpretable as a message key

defaultMessage - fallback default message

public void rejectWithErrorArgs(java.lang.String errorCode,
                                java.lang.Object[] errorArgs,
                                java.lang.String defaultMessage)

Description copied from interface: Errors

Description copied from interface: Errors

Register a field error for the specified field of the current object (respecting the current nested path, if any), using the given error description.

The field name may be null or empty String to indicate the current object itself rather than a field of it. This may result in a corresponding field error within the nested object graph or a global error if the current object is the top object.

Specified by:

rejectValue in interface Errors

Parameters:

field - the field name (may be null or empty String)

errorCode - error code, interpretable as a message key
